Sadly no. It's not even possible to *identify* all audio and video. So
many known and known-weird ways it could be smuggled around.
 Flash (.flv) for example is not video or audio. Its a script (yay^HH
boo for binary blobs).

Best you can hope for is rep_mime_type ACL check for video and audio
mime types. You will also need the Squid-3.5 store_miss feature to use
it for non-caching when it matches ("cache deny ..." wont work on
